NORWOOD, MA — December 8, 2006 — Books24x7®, a subsidiary of SkillSoft PLC (Nasdaq: SKIL) and the developer of online Referenceware® for IT, business, engineering, financial and government professionals, today announced that its EngineeringPro™ Referenceware collection now provides access to more than 1,000 engineering books. In addition to this important milestone, Books24x7 is pleased to announce four new publishing partners, AK Peters, Pennwell, Springer and Infinity Science Press, whose engineering titles will add even greater breadth and value to this collection.

Offering an online library of more than 1,000 engineering texts and resources, EngineeringPro provides instant access to relevant, reliable information for engineers across all disciplines, including aerospace, bioengineering, chemical, civil, electrical, mechanical, nanotechnology, nuclear and petroleum. Texts feature select tables downloadable into Microsoft Excel and LiveEquations, a powerful feature that leverages the power of MathML by enabling users to import equations into computational analysis packages for immediate use. Subscribers have access to the unabridged text of all titles in the collection, including new titles added throughout the subscription period. Subscribers can also take advantage of the ability to search for specific information using Books24x7’s unique multi-tier search engine for more informed decision making.

EngineeringPro is one of twelve topically-oriented subscription based Referenceware collections offered by Books24x7 to corporations and institutions. EngineeringPro complements Books24x7’s flagship product – ITPro – which serves the needs of programmers, network administrators, database developers and other technical professionals.

“In a little over one year, our usage of the EngineeringPro library has jumped considerably, where it is now approximately half of our usage of the ITPro library. I expect that our utilization of this wide spectrum library will continue to grow as the library grows and will eventually be just as important to us as the ITPro library,” said Philip Trudeau, Manager Technical Programs, MITRE Institute, MITRE Corporation.

Highlighted below is a sample of titles from the new publishing partners, as well as existing partner McGraw-Hill Professional, that are scheduled to be added to the EngineeringPro Collection before the end of 2006:
